本文对水力运输中水平管路的阻力损失理论进行了概括性分析,并根据抚顺的试验资料提出了新的阻力计算公式. 依据实验资料的分析,固体在水中参与扩散和摩擦,其大小与混合物比重r_混的1/2次方成比例.对与清水阻力损失规律不同的附加阻力损失,亦根据理论上的分析修正了已有的实验式. 文中引用了国内外有关实际资料对新公式进行了验算.并与其他公式进行了对比.检验的结果证明新公式更附合实际情况,应用范围亦比其他公式广泛. 依据新的阻力公式推导了新的临界流速公式,经与实际资料对比亦比现有各公式精确.
Based on the experimental data of Fushun, a new formula for calculating the resistance is proposed.According to the analysis of the experimental data, the solid participates in the diffusion and friction in the water, and its size and the mixture The ratio of the r_mixed 1/2 ratio is proportional to the loss of water resistance with a law of the additional loss of resistance is also based on the theoretical analysis to amend the existing experimental formula.This paper cites the actual data at home and abroad on the new formula The results of the test prove that the new formula is more practical and the scope of application is wider than other formulas.A new formula of critical flow rate is deduced according to the new resistance formula and compared with the actual data Than the existing formula accurate.
